Answer
given,
mass of student = 60 Kg
mass of suitcase = 10 Kg
a) Work done by picking of Suitcase is equal to zero
b) acceleration = 0.1 m/s²
distance = 2 m
Using second law conservation
F = m a
F = 10 x 0.1 = 1 N
c) Work done
W = F x s
W = 1 x 2 = 2 J
d) When the are moving with constant speed acceleration is equal to zero
F = m a
F = 10 x 0 = 0 N
W = F x s = 0 x s = 0 J
e) work done = change in kinetic energy
K.E = 2 J
De Broglie's identity gives the relationship between the momentum and the wavelength of a particle:

where
p is the particle momentum
m is its mass
v its velocity
h is the Planck constant

is the wavelength
By re-arranging the equation, we get

and by using the data about the proton, given in the text, we can find the proton's wavelength:
